The first screen 800 includes a title bar 801 displaying a name of a messenger application and a friend list screen 810. Registered friends 811 to 815 are separately displayed in the friend list screen 810. Each of the displayed friends 811 to 815 may include a name, a picture, a number of messages, a time of message receipt, and/or a part of a message.

In step S502 of FIG. 5, a second screen is displayed in a second touch screen.

More specifically, referring to FIG. 8A, a second screen 850 is displayed in the second touch screen 190 b. The second screen 850 a photo screen 860. The photo screen 860 may display multiple photos.

As illustrated in FIG. 8A, the first screen 800 and the second screen 850 are screens corresponding to separate applications executed in the apparatus 100.

In step S503 of FIG. 5, multiple touches are detected in the first touch screen.

More specifically, referring to FIG. 8A, a user inputs multiple touches 880 and 881 in the first touch screen 190 a of the apparatus 100. The controller 110 detects the multiple touches 880 and 881 using the first touch screen 190 a and the touch screen controller 195, or the first control unit 110 a detects the multiple touches 880 and 881 using the first touch screen 190 a and the first touch screen controller 195 a. The controller 110 or the first control unit 110 a may detect the multiple touches 880 and 881 based on a first time interval between the time of a first touch and the time of a later touch. For example, when the interval between a first and second touch is 1 second or less, the controller 110 or the first control unit 110 a determine that the input touches are multiple touches. However, the controller 110 or the first control unit 110 a determines that the input touches are not multiple touches, e.g., when the time interval between the multiple touches exceeds 1 second or a single touch is detected.

The controller 110 or the first control unit 110 a receives the positions 880 a and 881 a, e.g., coordinates (x, y), on the first screen 800 corresponding to the multiple touches 880 and 881 from the touch screen controllers 195 or 195 a, respectively.

Referring to FIG. 8A, the positions on the first screen 800 corresponding to the multiple touches 880 and 881 are in the friend list screen 810. The friend corresponding to the position of the touch 880 is identified, according to the setting of the apparatus 100, e.g. an order of the multiple touches, and displayed. The setting of the apparatus 100 may include the positions of the multiple touches, e.g., whether a selectable region exists or a lower level exists in a hierarchy structure. Further, when the apparatus 100 does not have the setting corresponding to the multiple touches, the controller 110 or the first control unit 110 a detects only the multiple touches. Differently from FIG. 8A, the regions corresponding to the positions of the multiple detected touches are displayed without discrimination.

In step S504 of FIG. 5, movements of the multiple touches in the first touch screen are detected.

Referring to FIG. 8A, the multiple touches 880 and 881 are drag & drop gestures or flick gestures in a direction of the second touch screen 190 b. more specifically, the controller 110 or the first control unit 110 a detects continuous movements of the multiple touches 880 and 881 contacting the first touch screen 190 by using the first touch screen 190 a and the touch screen controllers 195 and 195 a, respectively. The continuous movements of the multiple touches 880 and 881, e.g., movements from the positions 880 a and 881 a to the positions 880 b and 881 b, mean a part of continuous touch gestures, e.g., movements from the positions 880 a and 881 a to the positions 880 d and 881 d, of the multiple touches 880 and 881 in the first touch screen 190 a. Further, the continuous movements of the multiple touches 880 and 881, e.g., movements from the positions 880 c and 881 c to the positions 880 d and 881 d, mean a part of continuous touch gestures, e.g., movements from the positions 880 a and 881 a to the positions 880 d and 881 d, of the multiple touches 880 and 881 on the second touch screen 190 b.

The continuous movements of the multiple touches mean that the contacts are continuously maintained on the first touch screen 190 a and the second touch screen 190 b, except for the space 100 d through which the multiple touches 880 and 881 pass. The continuous movements of the multiple touches are separated in the space 100 d and the contacts of the continuous movements of the multiple touches maintained from the initial positions 880 c and 881 c on the space 100 d and the second touch screen 190 b are separated at the last positions 880 d and 881 d. Further, the continuous movements of the multiple touches mean a continuous movement of at least one touch of the multiple touches after the multiple touches 880 and 881 are input, e.g. a movement of the single touch from a position 880 a to a position 880 d, a movement of another single touch from a position 881 a to 881 b, or movements of the multiple touches from positions 880 a and 881 a to the positions 880 b and 881 b.

In step S505 of FIG. 5, the arrivals of the multiple touches to the second touch screen are detected.

Referring to FIG. 8A, the multiple touches 880 and 881 begin in the first touch screen 190 a and pass through the space 100 d between the first touch screen 190 a and the second touch screen 190 b to arrive the second touch screen 190 b.

The controller 110, or the first control unit 110 a and the second control unit 110 b detects the continuous movement of the multiple touches 880 and 881, e.g., the movements from the initial positions 880 a and 881 a to the last positions 880 d and 881 d, by using the first and second touch screens 190 a and 190 b and the touch screen controllers 195, 195 a, and 195 b. The controller 110, or the first control unit 110 a and the second control unit 110 b may recognize last positions 880 b and 881 b in the first touch screen 190 a of the multiple touches 880 and 881 and initial positions 880 c and 881 c of the arrival of the multiple touches 880 and 881 in the second touch screen 190 b.

The controller 110, or the first control unit 110 a and the second control unit 110 b detects the arrivals of the multiple touches 880 and 881 to the second touch screen 190 b based on a second time interval, e.g., a time for passing the space 100 d, a determined area, or a direction, e.g., a range of an allowable gradient.

FIGS. 10A and 10C are screen images illustrating an example of an arrival of a continuous touch according to an embodiment of the present invention.

Referring to FIGS. 10A and 10C, the arrivals of the multiple touches 880 and 881 within a second time interval T₂, e.g., 0.5 sec, may be detected using a time between a time t₁ at the last positions 880 b and 881 b in the first touch screen 190 a and a time t₂ of the initial positions 880 c and 881 c in the second touch screen 190 b, the arrivals of the multiple touches 880 and 881 in a determined area A₁ including the initial positions 880 c and 881 c in the second touch screen 190 b from the last positions 880 b and 881 b in the first touch screen 190 a may be detected, or the arrivals of the multiple touches 880 and 881 in an area within an allowable gradient range R₁ including the initial positions 880 c and 881 c in the second touch screen 190 b, based on a gradient θ₁ from the initial positions 880 a and 881 a to the last positions 880 b and 881 b of the multiple continuous touches 880 and 881 in the first touch screen 190 a may be detected.

Referring to FIG. 11B, the second time interval T₂ may be changed using a time interval 1112 of the multiple-touch setting 1110.

Referring to FIG. 10B, the determined area A₁ is a radius of 3 cm based on the positions in the second touch screen 190 b extended from the last positions 880 b and 881 b in the first touch screen 190 a. Further, the determined area may have a polygonal shape, e.g., a polygon having 3 cm in width and 6 cm in length. The determined areas of the respective touches 880 and 881 may be overlaid.

Referring to FIG. 11B, the determined area A₁ may be changed using a radius 1113 of the determined area of the multiple-touch setting 1110.

Referring to FIG. 10C, the allowable gradient range R₁ means second gradients θ₂ and θ₃, e.g., a range of ±45°. For example, when an angle of the first gradient θ₁, i.e., a gradient of a straight line from the initial positions 880 a and 881 a in the first touch screen 190 a to the last positions 880 b and 881 b, of the multiple continuous touches 880 and 881 is 15°, the initial positions 880 c and 881 c in the second touch screen 190 b are within an area in which the angles of the second gradients θ₂ and θ₃, i.e., the gradients between the last positions 880 b and 881 b in the first touch screen 190 a and the initial positions in the second touch screen 190 b, ranges from 60° to −30°. The allowable gradient ranges of the respective touches 880 and 881 may be overlaid.

Referring to FIG. 11B, the allowable gradient range R₁ may be changed using an allowable gradient range 1114 of the multiple-touch setting 1110.

The controller 110, or the first control unit 110 a and the second control unit 110 b may provide the user with feedback in response to the arrivals of the multiple touches 880 and 881 at the positions 880 c and 881 c in the second touch screen 190 b. Additionally, a visual feedback, an auditory feedback, and/or a tactile feedback may be provided.

For example, the visual feedback may be displayed in the first touch screen 190 a or the second touch screen 190 a as a screen change effect, e.g., fading, pushing, or covering, in response to the arrivals of the multiple touches 880 and 881 at the positions 880 c and 881 c in the second touch screen 190 b. The auditory feedback may be output as a sound in response to the arrivals of the multiple touches 880 and 881 at the positions 880 c and 881 c in the second touch screen 190 b through the first speaker 163 a or the second speaker 163 b. The tactile feedback may be output as vibration in response to the arrivals of the multiple touches 880 and 881 at the positions 880 c and 881 c in the second touch screen 190 b by the vibration motor 164.

Referring to FIG. 11B, a time, e.g., 1 sec, of providing the user with at least one feedback and the selection of the feedback, e.g., selection of at least one from the visual feedback, the auditory feedback, and the tactile feedback, may be changed using a feedback setting 1116 of the multiple-touch setting 1110.

In step S506 of FIG. 5, a second screen of the second touch screen is changed.

Referring to FIG. 8A, the controller 110 or the second control unit 110 b change a second screen 850 to a third screen 820 in response to the arrivals of the multiple touches 880 and 881 at the positions 880 c and 881 c in the second touch screen 190 b. The third screen 820 corresponds to the first screen 80. For example, the third screen 820 is a detailed screen of the friend 811 displayed in the friend list screen 810. The third screen 820 includes a name region 821 for displaying a photo of a friend and a message region 822 for displaying a time of receipt/transmission of a message from/to a friend and contents 823 of the received/transmitted message.

According to an embodiment of the present invention, the change from the second screen 850 to the third screen 820 is that both the first and second touch screens 190 a and 190 b are displayed with the screens 810 and 820 corresponding to a single application, i.e., the application originally on the first touch screen 190 a. The change from the second screen 850 to the third screen 820 may be completed before the continuous movements of the multiple touches 880 and 881 are completed at the positions 880 d and 881 d.
